Abstract
Mangled extremities are a challenging problem for the orthopaedic surgeon. The decision for salvage versus amputation is multifactorial. Several work groups have attempted to create scoring systems to guide treatment, but each case must be regarded individually. As surgical technique and prosthetics continue to improve, amputations should be seen as a viable reconstructive option, rather than failure. This article reviews scoring systems for the mangled extremity, outcomes on salvage versus amputation, amputation surgical technique, and prosthetic options.

Abstract
BACKGROUND Recent progress in biomechatronics and vascularized composite allotransplantation have occurred in the absence of congruent advancements in the surgical approaches generally utilized for limb amputation. Consideration of these advances, as well as of both novel and time-honored reconstructive surgical techniques, argues for a fundamental reframing of the way in which amputation procedures should be performed. METHODS We review sentinel developments in external prosthetic limb technology and limb transplantation, in addition to standard and emerging reconstructive surgical techniques relevant to limb modification, and then propose a new paradigm for limb amputation. RESULTS An approach to limb amputation based on the availability of native tissues is proposed, with the intent of maximizing limb function, limiting neuropathic pain, restoring limb perception/proprioception and mitigating limb atrophy. CONCLUSIONS We propose a reinvention of the manner in which limb amputations are performed, framed in the context of time-tested reconstructive techniques, as well as novel, state-of-the-art surgical procedures. Implementation of the proposed techniques in the acute setting has the potential to elevate advanced limb replacement strategies to a clinical solution that perhaps exceeds what is possible through traditional surgical approaches to limb salvage. We therefore argue that amputation, performed with the intent of optimizing the residuum for interaction with either a bionic or a transplanted limb, should be viewed not as a surgical failure, but as an alternative form of limb reconstruction.

Abstract
BACKGROUND This literature review was undertaken to determine if commonly held views about the benefits of a bone bridge technique are supported by the literature. METHODS Four databases were searched for articles pertaining to surgical strategies specific to a bone bridge technique of the transtibial amputee. A total of 35 articles were identified as potential articles. Authors included methodology that was applied to separate topics. Following identification, articles were excluded if they were determined to be low quality evidence or not pertinent. RESULTS Nine articles were identified to be pertinent to one of the topics: Perioperative Care, Acute Care, Subjective Analysis and Function. Two articles sorted into multiple topics. Two articles were sorted into the Perioperative Care topic, 4 articles sorted into the Acute Care topic, 2 articles into the Subjective Analysis topic and 5 articles into the Function topic. DISCUSSION There are no high quality (level one or two) clinical trials reporting comparisons of the bone bridge technique to traditional methods. There is limited evidence supporting the clinical outcomes of the bone bridge technique. There is no agreement supporting or discouraging the perioperative and acute care aspects of the bone bridge technique. There is no evidence defining an interventional comparison of the bone bridge technique. CONCLUSION Current level III evidence supports a bone bridge technique as an equivalent option to the non-bone bridge transtibial amputation technique. Formal level I and II clinical trials will need to be considered in the future to guide clinical practice. Clinical relevance Clinical Practice Guidelines are evidence based. This systematic literature review identifies the highest quality evidence to date which reports a consensus of outcomes agreeing bone bridge is as safe and effective as alternatives. The clinical relevance is understanding bone bridge could additionally provide a mechanistic advantage for the transtibial amputee.

Abstract
BACKGROUND People with transtibial amputation stand ~50times/day. There are two general approaches to transtibial amputation: 1) distal tibia and fibula union using a "bone-bridge" (Ertl), 2) non-union of the tibia and fibula (Non-Ertl). The Ertl technique may improve functional outcomes by increasing the end-bearing ability of the residual limb. We hypothesized individuals with an Ertl would perform a five-time sit-to-stand task faster through greater involvement/end-bearing of the affected limb. METHODS Ertl (n=11) and Non-Ertl (n=7) participants sat on a chair with each foot on separate force plates and performed the five-time sit-to-stand task. A symmetry index (intact vs affected limbs) was calculated using peak ground reaction forces. FINDINGS The Ertl group performed the task significantly faster (9.33s (2.66) vs 13.27 (2.83)s). Symmetry index (23.33 (23.83)% Ertl, 36.53 (13.51)% Non-Ertl) indicated the intact limb for both groups produced more force than the affected limb. Ertl affected limb peak ground reaction forces were significantly larger than the Non-Ertl affected limb. Peak knee power and net work of the affected limb were smaller than their respective intact limb for both groups. The Ertl intact limb produced significantly greater peak knee power and net work than the Non-Ertl intact knee. INTERPRETATION Although loading asymmetries existed between the intact and affected limb of both groups, the Ertl group performed the task ~30% faster. This was driven by greater power and work production of the Ertl intact limb knee. Our results suggest that functional differences exist between the procedures.

Abstract
The optimal technique for a transtibial amputation in a young, active, and healthy patient is controversial. Proponents of the Ertl procedure (in which the cut ends of the tibia and fibula are joined with a bone bridge synostosis) argue that the residual limb is more stable which confers better prosthetic fit and improved function especially among high-performing individuals. At the same time, the Ertl procedure is associated with longer operative and healing time and may be associated with a higher complication rate compared with the standard Burgess procedure. The TAOS is a prospective, multicenter randomized trial comparing 18-month outcomes after transtibial amputation using the Ertl versus Burgess approach among adults aged 18 to 60. The primary outcomes include surgical treatment for a complication and patient-reported function. Secondary outcomes include physical impairment, pain, and treatment cost.

Abstract
Traumatic and trauma-related amputations represent unfortunate sequelae of severe injury, but should not be viewed as a treatment failure and may represent the best reconstructive option for some patients. Lessons from recent military conflicts have guided the evolution of modern surgical techniques and rehabilitation management of this challenging patient population, and treatment at a specialty center may improve patient outcomes. Despite appropriate management, however, surgical complications remain common and revision surgery is often necessary. Bridge synostosis procedures remain controversial, and clinical equipoise remains regarding their functional benefits. Based on European experience over the last 3 decades, osseointegration has evolved into a viable clinical alternative for patients unable to achieve acceptable function using conventional sockets, and several devices are being developed or tested in the United States. Targeted muscle reinnervation and advanced pattern recognition may dramatically improve the functional potential of many upper extremity amputees, and the procedure may also relieve neuroma-related pain. Furthermore, exciting new research may eventually facilitate haptic feedback and restore useful sensation for amputees. Natural disasters and global terrorism events, in addition to conventional trauma resulting in limb loss, make a working knowledge of current amputation surgical techniques essential to the practicing orthopaedic trauma surgeon.

Abstract
Amputation may be required for management of lower extremity trauma and medical conditions, such as neoplasm, infection, and vascular compromise. The Ertl technique, an osteomyoplastic procedure for transtibial amputation, can be used to create a highly functional residual limb. Creation of a tibiofibular bone bridge provides a stable, broad tibiofibular articulation that may be capable of some distal weight bearing. Several different modified techniques and fibular bridge fixation methods have been used; however, no current evidence exists regarding comparison of the different techniques. Additional research is needed to elucidate the optimal patient population, technique, and postoperative protocol for the Ertl osteomyoplastic transtibial amputation technique.

Combat-related bridge synostosis versus traditional transtibial amputation: comparison of military-specific outcomes. Strategies Trauma Limb Reconstr 2015; 11:5-11.

Abstract
The aim of our study was to determine military-specific outcomes for transtibial amputations of US Service members using either the traditional technique (Burgess) or the Ertl technique. All US Service members sustaining transtibial, combat-related amputation from September 2001 through July 2011 were reviewed. Amputation type, mechanism of injury, time interval to amputation, age, sex, branch of service, rank, force, nature, and injury severity score were recorded. Outcomes were determined by analyzing military-specific medical review results, to include the following: Physical Evaluation Board Liaison Office (PEBLO) rating (0–100), PEBLO outcome (permanent retirement, temporary disability retirement, separation without benefits, continuation of active duty, or fit for redeployment), and the rate of redeployment. Amputation type (Ertl vs. Burgess) was determined by reviewing postoperative radiographs and radiology reports. Data from all of the above categories were compared for both Ertl and Burgess amputees. Of 512 subjects identified, 478 had radiographs or radiology reports distinguishing between Ertl or Burgess transtibial amputation. A total of 406 subjects underwent the Burgess procedure, and 72 subjects underwent the Ertl procedure. There was not a significant difference between the two groups in review board rating (p = 0.858), review board outcome (p = 0.102), or ability to deploy (p = 0.106); however, subjects that underwent the Ertl procedure remained on active duty at a significantly higher rate (p = 0.021). There is a higher rate of remaining on active duty using the Ertl technique. This study suggests that there is an improvement in functional outcome with the Ertl technique.

Abstract
BACKGROUND After a decade of war in Iraq and Afghanistan, we have observed an increase in combat-related injury survival and a paradoxical increase in injury severity, mainly because of the effects of blasts. These severe injuries have a devastating effect on each patient's immune system resulting in massive upregulation of the systemic inflammatory response. By examining inflammatory mediators, preliminary data suggest that it may be possible to correlate complications such as wound failure and heterotopic ossification (HO) with distinct systemic and local inflammatory profiles, but this is a relatively new topic. QUESTIONS/PURPOSES We asked whether systemic or local markers of inflammation could be used as an objective means, independent of demographic and subjective factors, to estimate the likelihood of (1) HO and/or (2) wound failure (defined as wounds requiring surgical débridement after definitive closure, or wounds that were not closed or covered within 21 days of injury) in patients sustaining combat wounds. METHODS Two hundred combat wounded active-duty service members who sustained high-energy extremity injuries were prospectively enrolled between 2008 and 2012. Of these 200 patients, 189 had adequate followups to determine the presence or absence of HO, and 191 had adequate followups to determine the presence or absence of wound failure. In addition to injury-specific and demographic data, we quantified 24 cytokines and chemokines during each débridement. Patients were followed clinically for 6 weeks, and radiographs were obtained 3 months after definitive wound closure. Associations were investigated between these markers and wound failure or HO, while controlling for known confounders. RESULTS The presence of an amputation (p < 0.001; odds ratio [OR], 6.1; 95% CI. 1.63-27.2), Injury Severity Score (p = 0.002; OR, 33.2; 95% CI, 4.2-413), wound surface area (p = 0.001; OR, 1.01; 95% CI, 1.002-1.009), serum interleukin (IL)-3 (p = 0.002; OR, 2.41; 95% CI, 1.5-4.5), serum IL-12p70 (p = 0.01; OR, 0.49; 95% CI, 0.27-0.81), effluent IL-3 (p = 0.02; OR, 1.75; 95% CI, 1.2-2.9), and effluent IL-13 (p = 0.006; OR, 0.67; 95% CI, 0.50-0.87) were independently associated with HO formation. Injury Severity Score (p = 0.05; OR, 18; 95% CI, 5.1-87), wound surface area (p = 0.05; OR, 28.7; 95% CI, 1.5-1250), serum procalcitonin ([ProCT] (p = 0.03; OR, 1596; 95% CI, 5.1-1,758,613) and effluent IL-6 (p = 0.02; OR, 83; 95% CI, 2.5-5820) were independently associated with wound failure. CONCLUSIONS We identified associations between patients' systemic and local inflammatory responses and wound-specific complications such as HO and wound failure. However, future efforts to model these data must account for their complex, time dependent, and nonlinear nature. LEVEL OF EVIDENCE Level II, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND There is a paucity of objectively recorded data delineating the pattern of weightbearing distribution within the prosthetic socket of patients with transtibial amputation. Our current knowledge is based primarily on information obtained from finite element analysis computer models. METHODS Four high-functioning transtibial amputees were fit with similar custom prosthetic sockets. Three load cells were incorporated into each socket at high stress contact areas predicted by computer modeling. Dynamic recording of prosthetic socket loading was accomplished during rising from a sitting position, stepping from a 2-leg stance to a 1-leg stance, and during the initiation of walking. By comparing the loads measured at each of the 3 critical locations, anterior/posterior shear, superior/inferior shear, and end weightbearing were recorded. RESULTS The same load pattern in all 4 subjects was found during each of the 3 functional activities. The load transmission at the distal end of the amputation residual limbs was negligible. Consistent forces were observed in both the anterior/posterior and superior/inferior planes. Correlation coefficients were used to compare the loads measured in each of the 4 subjects, which ranged from a low of .82 to a high of .98, where a value approaching 1.0 implies a linear relationship amongst subjects. CONCLUSION This experimental model appears to have accurately recorded loading within a transtibial prosthetic socket consistent with previously reported finite element analysis computer models. CLINICAL RELEVANCE This clinical model will allow objective measurement of weightbearing within the prosthetic socket of transtibial amputees and allow objective comparison of weightbearing distribution within the prosthetic sockets of patients who have undergone creation of different versions of a transtibial amputation residual limb and prosthetic socket designs.

Abstract
OBJECTIVE Complication rates leading to reoperation after trauma-related amputations remain ill defined in the literature. We sought to identify and quantify the indications for reoperation in our combat-injured patients. DESIGN Retrospective review of a consecutive series of patients. SETTING Tertiary Military Medical Center. PATIENTS/PARTICIPANTS Combat-wounded personnel sustaining 300 major lower extremity amputations from Operations Iraqi and Enduring Freedom from 2005 to 2009. INTERVENTION We performed a retrospective analysis of injury and treatment-related data, complications, and revision of amputation data. Prerevision and postrevision outcome measures were identified for all patients. MAIN OUTCOME MEASUREMENTS The primary outcome measure was the reoperation on an amputation after a previous definitive closure. Secondary outcome measures included ambulatory status, prosthesis use, medication use, and return to duty status. RESULTS At a mean follow-up of 23 months (interquartile range: 16-32), 156 limbs required reoperation leading to a 53% overall reoperation rate. Ninety-one limbs had 1 indication for reoperation, whereas 65 limbs had more than 1 indication for reoperation. There were a total of 261 distinct indications for reoperation leading to a total of 465 additional surgical procedures. Repeat surgery was performed semiurgently for postoperative wound infection (27%) and sterile wound dehiscence/wound breakdown (4%). Revision amputation surgery was also performed electively for persistently symptomatic residual limbs due to the following indications: symptomatic heterotopic ossification (24%), neuromas (11%), scar revision (8%), and myodesis failure (6%). Transtibial amputations were more likely than transfemoral amputations to be revised due to symptomatic neuromata (P = 0.004; odds ratio [OR] = 3.7; 95% confidence interval [95% CI] = 1.45-9.22). Knee disarticulations were less likely to require reoperation when compared with all other amputation levels (P = 0.0002; OR = 7.6; 95% CI = 2.2-21.4). CONCLUSIONS In our patient population, reoperation to address urgent surgical complications was consistent with previous reports on trauma-related amputations. Additionally, persistently symptomatic residual limbs were common and reoperation to address the pathology was associated with an improvement in ambulatory status and led to a decreased dependence on pain medications.

Abstract
OBJECTIVES Much attention has been given to lower extremity amputations that occur more than 90 days after injury, but little focus has been given to analogous upper extremity amputations. The purpose of this study was to determine the reason(s) for desired amputation and the common complications after amputation for those combat-wounded service members who underwent late upper extremity amputation. DESIGN Retrospective case series. SETTING Tertiary trauma center. PATIENTS/PARTICIPANTS All US service members who sustained major extremity amputations from September 2001 to July 2011 were analyzed. INTERVENTION Late (>90 days after injury) upper extremity amputations. MAIN OUTCOME MEASUREMENTS Amputation level(s), time to amputation, age, number of operations, pre/postoperative complications, reason(s) for desiring amputation, and disability outcomes were analyzed. RESULTS Seven of 218 (3.2%) upper extremity amputees had a late upper extremity amputation (>90 days from injury to amputation). The mean and median number of days from injury to amputation was 689 and 678, respectively. The most common preamputation complications were loss of wrist or finger motion (7, 100%), neurogenic pain (4, 57%), and heterotopic ossification (4, 57%). Three (43%) patients (2 persistent and 1 new onset) had neurogenic pain and 2 (29%) had heterotopic ossification after amputation. Only 57% (4 of 7) of amputees used their prostheses regularly. CONCLUSIONS Service members undergoing late upper extremity amputation seem to have different pre- and postoperative complications than those patients undergoing late lower extremity amputations. It was common for the amputee to not wear their prostheses and to experience similar complications after amputation, albeit in a less severe form.

Abstract
Symptomatic distal tibiofibular instability is a known complication of trauma-related transtibial amputations. Overt proximal tibiofibular dislocations, which are easily recognized on routine radiographs, may occur concurrently with the traumatic injury or amputation. More commonly, however, the proximal tibiofibular joint remains structurally intact in the presence of distal instability due to the loss of the distal syndesmotic structures and damage to the interosseous membrane, resulting in fibular angulation and distal tibiofibular diastasis. Some authors have espoused treating this instability with the creation of a distal tibiofibular bridge synostosis (the so-called Ertl procedure or modifications there of) to prevent potentially painful discordant motion and to minimize the prominence of the residual distal fibula. Recent studies, however, have suggested an increase in complication and reoperation rates in transtibial amputations that received a bridge synostosis compared with standard transtibial amputations. Additionally, although there are several described techniques for bridge synostosis creation, most are dependent on having sufficient remaining fibula to construct the bone bridge without unnecessary shortening of the tibia; however, sufficient residual fibula is not always available after traumatic and trauma-related amputations. We propose a technique utilizing a suture bridge to restore tibiofibular stability when performing transtibial amputations in patients with proximal tibiofibular dislocations or distal diastasis, avoiding the potential need for a distal bridge synostosis.

Abstract
BACKGROUND Amputation revision rates following major upper-extremity amputations have not been previously reported in a large cohort of patients. We hypothesized that the revision rates following major upper-extremity amputation were higher than the existing literature would suggest, and that surgical treatment of complications and persistent symptoms would lead to improved outcomes. METHODS We performed a retrospective analysis of a consecutive series of ninety-six combat-wounded personnel who had sustained a total of 100 major upper-extremity amputations in Operation Iraqi Freedom and Operation Enduring Freedom. Prerevision and postrevision outcome measures, including prosthesis use and type, the presence of phantom and residual limb pain, pain medication use, and return to active military duty, were identified for all patients. RESULTS All amputations resulted from high-energy trauma, with 87% occurring secondary to a blast injury. Forty-two residual limbs (42%) underwent a total of 103 repeat surgical interventions. As compared with patients with all other levels of amputation, those with a transradial amputation were 4.7 (95% confidence interval [CI]: 1.75 to 12.46) times more likely to have phantom limb pain and 2.8 (95% CI: 1.04 to 7.39) times more likely to require neuropathic pain medications. In the group of patients who underwent revision surgery, regular prosthesis use increased from 19% before the revision to 87% after it (p < 0.0001). CONCLUSIONS In our cohort, revision amputation to address surgical complications and persistently symptomatic residual limbs improved the patient's overall acceptance of the prosthesis and led to outcomes equivalent to those following amputations that did not require revision.
